摘要

Combining heavy quark effective theory and the chiral Lagrangian approach we investigate D meson radiative decays. First, we reanalyse DDγD^{*} \rightarrow D \gamma decays using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. Then, we calculate branching ratios DVγD \rightarrow V \gamma. We make some comments on the Cabbibo suppressed decays Dρ/ωγD \to \rho / \omega \gamma and the branching ratios of DPPγD \rightarrow P P \gamma decays.
